To @ZZ whom t may concern:

Beitknown that I, WALTER WAGNER, a citizen of the United States, residing at Chicago, in the county of Cook` and State of Illinois, have invented certain new and useful Improvements in Can-SolderingMachines, which are fully set forth in the following specication, reference being had to the accompanying drawings, forminga part hereof, in which- Figure 1 shows'my improved can-soldering machine in plan view, the upper partsl of the frames being broken away and all other machinery removed except the circular and in part spiral cams which guide the can-carriers and the cans and soldering-troughs. The machine is shown full of cans. Fig. 2 shows a fragment of the revolving ring with arm or hanger k and wi pers with their levers s. Fig. 3 shows a horizontal section through a hanger or arms 7c and s', the wiper working on the can. Fig. 4 shows a vertical section taken on the plane ww of Fig. 1, which is at or near the point where cans enter into the machine.

' In this and all similar sections ,the cans are the revolving ring.

moving from the observer and the right-hand cans are on the inner and the opposite cans on the outer circle as they move in the machine. An inside can is passing through the soldering-trough. The outer can is yet unsecured between the chucks. Fig. 4A shows in side elevation, as seen from the outside1 of the machine, the cam which operates the mechanism which actuates the movable chuck of the can-carrier. Fig. 5 shows a vertical section taken on the line xm of Fig. 1. Here the outside can is undergoing the soldering operation while the inside can is being wiped. It also shows the mechanism which drives Fig. 6 shows a vertical section on the plane y 'y' of Fig. l. Here the outside can is being wiped while the now finished inside can is being cooled. Fig. 6A shows a longitudinal elevation of a portion of the cam, as. seen from the outside, which operates the mechanism to which the canwiper is attached. Fig. `'7 shows a vertical section on the line z z', Fig.` 1. Here the ontside can of the preceding ligure has advanced and ascended and moved into a horizontal position, while the inside can has descended and also moved into the horizontal position, at which point it is about to be discharged from the machine. Fig. 7A shows in plan view the cam which operates the mechanism which discharges the can from the machine. Fig. 8 shows an outside elevation, between frames l and 6, of that part of the machine where the can-carriers change their said relative circular positions-that is to say, the outer carriers go to the inner and the inner carriers to the outer circle, and thus bring the opposite ends of those cans thus sent to the inner circle into the soldering-trough, and at the same time the cans finished on the inner circle are sent outward and discharged near the point where they first entered the outer circle. Fig. 9 shows a sido elevation of a solderingtrough with its end supports and vertical adjusting-screws. Fig. 10 shows a vertical section of Fig. l, the cutting plane being in front of the frames 2 and 5, only-enough hangers with cans being shown to illustrate the matter sufficiently and avoid confusion. Fig. ll shows an exterior view of my machine with the outer circle of cams and parts connected with it only developed into a plane, fraime 1 and a fragment of cam a2 being repeated. Fig. 12 shows the inner circle of cams, as seen from the interior or center of the circle, and parts connected with it only developed into a plane, frame 1 and a part of cam c being repeated, the repetition of frame 1 and cams being made to show more fully and clearly the several parts. The arrows inboth figures indicate the same motion of the cams.

Like letters and figures refer to like parts.

The object of my invention is to produce a soldering-machine of that class whereof the form is circularvand in which the cans move in a series of concentric circles and wherein the cans undergo a complete operation and discharge from the machine, and, to thus save a vast amount of room and cost of production of such a machine.

To attain said desirable ends I make use of a rotating horizontal carrier, or ring h, from which depend fixed hangers, or arms, holding can-ctrriers placed radially and so as to form inner and outer, or concentric circles of cans, and said circles of cans are adapted to change, at fixed places, from one circle to the other and end for end into the soldering trough after which they are wiped, cooled and discharged from the machine.

ICO

I construct my said machine in substantially the following manner, namely: Its frame work consists of a series of cast iron frames 1, 2, 3, 4, 5, 6; set radially and equidistant from a point, and are connected by and support a circular track, g, on which, on rollers, h', rotates an annular carrier, h, with gear-teeth Z and dependent tlxed arms k,which support between them, on pins 2 radially revolving can-carriers, t', which are actuated by means of fixed cams a, b, b', b2, b3, c, c', d, d2, a,a2, also supported by said frames. 'One of said frames (4) carries a shaft m with pinion, m, which engages the teeth, l, and a fixed pulley, m2, and loose pulley, m3, to actuate said carrier.

In Fig. 1 the cans, j, are represented by circles and by shaded cylinders, where they are inclined to the line of sight. The can ends thus shown may also be regarded as the geometrical representation of the chucks, t', which hold the cans, because the position of the one indicates the position of the other and each represents the position of the cancarrier, t', which holds the can. Said chucks or plates, il', are shown with the can-carrier, ,on enlarged scales in Figs. 4, 5, 6, and 7, and are also shown in Fig. 8. All details are omitted from Fig. 1, because the parts there represented are thus more easily understood.

From the preceding statement a sufficiently clear idea has been given to show the operations a can undergoes in passing through the machine, omitting, for the present the details of mechanism required to complete the operation.

Looking at the machine between the frames, 1 and 6, Figs. 1 and 8, we see a pair of chucks, plates, or heads, i', near 1, open to receive a can, vertically, and supplied with a can in Fig. 4, which approach and clamp cans placed between them, when slightly advanced from said position as indicated.

The cam, a, holds the spindle of the lower chuck or head t', and thus the carrier t' and its can, j, in an erect position (see left hand can in Fig. 4) until it gets near 3. At that point the said cam ends and the end of the upper spindle enters a curved and slotted cam, b, which moves the can outward around the pin, or center, 2, upon which the carrier turns to incline it, as shown in Figs. 1 and 5. At the end of said cam, b, begins a rack, b',

which engages the pinion f2, on the uppery spindle of each carrier t'. In said position the lowest corner of the can dips into and revolves in a trough, o, ot' melted solder. Said trough, and rack, terminate near 4, where the rack forms an upwardly and inwardly curved cam, b2, which again erects the can. At the termination of the short part, b2, begins the part h3, which, with a corresponding inside part forms the circular and slotted cam b3, similar to the ca m, a, which extends to about the central plane of 6. Directly under the cam b3 begins a cam c, which engages the spindle of the opposite or lower end. Said cam bends outwardly, and extends upward, at the same time curving inward, spirally as abruptly as possible, and far enough to turn the axis ot' the can into the horizonal position, shown by the upper can, in Fig. '7, where, or slightly farther on, said cam terminates and at said point the opposite spindie enters the slotted cam, c', which, from said point, descends about as abruptly as the cam, c, asoends, and the ends of the can are thus reversed. At this point the lower cam, c', terminates and the upper cam, d, begins and receives the upper end of the spindle and brings the can-carrier down into the position shown in Fig. 4, where the pinion d engages with the rack d, which rotates the can. Said rack terminates with an upwardly rising and outwardly turning part d2 which sets the can vertical, from whence said cam continues in a horizontal position and circular form and with a corresponding outer piece forms the slotted cam a, terminating in about the same radial plane as b3. At said latter point said cam twists and curves abruptly into a part a2 which reaches over to and joins the cam, a, near 1, of which it is, in fact, a part, the parts d,

d2, a', a2, and a, forming one connected piece.

Through said cam, d2, the can-carrier receives a half-revolution and is thus brought into its original position ready to receive another can. When the cans have been soldered in the troughs o, o', they must revolve axially for the purposes of both wiping and cooling them. This is accomplished by providing rack-teeth, r, under the exterior member of the cam, b3, and rack teeth, T', for the interior member ot the cam, a; the pinion f2, engaging with the rack r, and the pinion d with the rack r', a pipe, p, throwing a cold air-blast against the last soldered joint to cool it sufticiently before the can is dropped out ofthe machine.

Wipers, s, wipe the cans when soldered and again erect. Each wiper is operated by a bell-crank lever, s', pivoted at s2, on arm, 7c, and operated by a slotted and circular cam,

t, under the track, g, which receives the roller,v

S3, on shorter arm of vsaid lever. By varying the vertical position of said cam, or parts of it, the wiper s, will engage with and wipe on the inner or outer circle of cans. In Figs. 4 and7 the roller ss is free. Hence the wiper hangs midway between the two circles of cans. In Fig. 5 the cam, t, is above the pin s2. Hence the wipers work upon the inner circle of cans. In Fig. 6 it is below the said pivot. Therefore the wipers work upon the outer circle of cans.

The chucks t" are adjusted in any well know-n manner for the particular height of cans. One chuck in each carrier is operated by a lever i3 fulcrumed at i4 and holding a collar 115, at its outer end, on the chuck spindle. The free end of said leveris moved out- 'Ward by a spring 116 and said lever is moved oppositely1 by a cam, u, when the chucks are to open to receivhea can; and, closed and held by the spring, t6, when released from said IOO IIO

cam, u, and again opened by the short cam u when the cans are to be dropped from the machine.

The soldering troughs, o, o', are supported on a frame-work, q, which also carries the gasburners. They are permanently adjusted to each other. Said frame-work is supported at its four corners by vertical adjusting screws, o, which stand on radially adjustable bars w, supported on beams fw', w', on the frames 4, 5, 6. Said barsfw, and beams w are connected by screws 'to2 whereby the troughs o, o, can be moved toward or from 'the center of the machine.

The cans, shownin Fig. 7, above each other, are shown in Fig.8 atjgjo, and in Fig. l by the single canjo. The upper can is shown in Figs. 7 and 8. Said upper can came from the cam b3 which passed it into the inclined cam, c, as jm,j, j?, and from which it passed into the cam, c', as,j1,j1, which, if followed into the position shown in Fig. 4, would be shown at jf.

The finished cans, after they have passed through the inner `circle of cams, duc., come from the cam, a', into cam, c2, as can j2,j,j, which brings them into the position shown in Fig. 7 where they are dropped from the machine onto the incline p". From thence the now empty chucks pass on into an inclined and then erect position and into the cam, a, as shown in Figs.4 and 8 where,in the latter place the can is already in position to be secured between the chucks and to pass on into the soldering-trough, o, thence to the inner soldering-,trough o and thence out of the machine, as before pointed out.

The now known can-soldering machines have but one circle of can carriers and they do not revolve in a complete, but only in a partial circle which also requires manual assistance to complete such motion.

The form of my carrier is substantially that of a machinists parallel clamp resembling the half of a lengthwise divided frame the axes of the chucks being coincident with that of the screw, in the open side of the frame. rPhe axes on which the carrier rotates is, transverse to its plane, in a lug back of, or opposed, to the open edge of said frame.
